Diagnostic Trouble Code (DTC) Charts and Descriptions
P0341 - Camshaft Position Sensor A Circuit Range/Performance (Bank 1 Or Single Sensor)
Description: This DTC sets when the CMP11 circuit has a noisy signal. For additional camshaft position (CMP) sensor
location information, refer to Section 1, Engine Control Components.
Possible Causes: • Radio frequency interference or electromagnetic interference
• Damaged camshaft phaser and sprocket
• Damaged camshaft position bank 1 sensor 1 (CMP11) shielding
Diagnostic Aids: Harness routing, harness alterations, incorrect shielding, or electrical interference from other systems may have
an intermittent impact on the CMP signal.
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test DR.
P0344 - Camshaft Position Sensor A Circuit Intermittent (Bank 1 Or Single Sensor)
Description: This DTC sets when the CMP11 circuit signal is intermittent. For additional camshaft position (CMP) sensor
location information, refer to Section 1, Engine Control Components.
Possible Causes: • Intermittent open circuit
• Intermittent short circuit
• Camshaft timing incorrectly set
• Camshaft position sensor trigger wheel out of alignment
• Damaged CMP sensor shielding
• Incorrect harness connections
• Corrosion
• Damaged camshaft position bank 1 sensor 1 (CMP11)
Diagnostic Aids: Harness routing, harness alterations, incorrect shielding, or electrical interference from other systems may have
an intermittent impact on the CMP signal.

All GO to Pinpoint Test DR.
P0345 - Camshaft Position Sensor A Circuit (Bank 2)
Description: This DTC sets when the CMP21 circuit signal cannot be detected. For additional camshaft position (CMP)
sensor location information, refer to Section 1, Engine Control Components.
Possible Causes: • CMP21 circuit open
• CMP21 circuit short to ground
• CMP21 circuit short to voltage
• SIGRTN circuit open
• VRSRTN circuit open
• CMP21 circuit shorted to other CMP circuits (2 or more CMP sensor systems)
• Camshaft timing incorrectly set
• Camshaft position sensor trigger wheel out of alignment
• Damaged CMP sensor shielding
• Camshaft position bank 2 sensor 1 (CMP21) incorrectly installed
• Damaged CMP21 sensor
Diagnostic Aids: Harness routing, harness alterations, incorrect shielding, or electrical interference from other systems may have
an intermittent impact on the CMP signal.
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test DR.
P0346 - Camshaft Position Sensor A Circuit Range/Performance (Bank 2)
Description: This DTC sets when the CMP21 circuit has a noisy signal. For additional camshaft position (CMP) sensor
location information, refer to Section 1, Engine Control Components.
Possible Causes: • Radio frequency interference or electromagnetic interference
• Damaged camshaft phaser and sprocket
• Damaged camshaft position bank 2 sensor 1 (CMP21) shielding
Diagnostic Aids: Harness routing, harness alterations, incorrect shielding, or electrical interference from other systems may have
an intermittent impact on the CMP signal.
